DIXIE CHICKS singer Natalie Maines is forced to take taxis when she visits New York City, because she can't understand the underground rail system. The READY TO RUN country star regrets she is forced to take the more expensive, slower form of transport, because she always gets lost on the subway. Maines tells London's Time Out magazine, "Well if I could figure out the New York subway system, I'd use it all the time. "I've got lost every single time I've tried to take the subway without my husband (Adrian Pasdar). I always seem to get on the one that's changed its route but they haven't changed the map."
